The value of administering a deep neuromuscular block (NMB) to reach a post-tetanic count (PTC) of < 4 during laparoscopy is not clear. Some anesthesiologists claim that certain laparoscopic procedures do not need NMB at all and that surgeons cannot objectivize the existence of insufficient workspace and the effect of NMB. They assume that deep anesthesia with remifentanyl improves also the workspace. This assumption may be based on the fact that deep anesthesia prevents spontaneous active muscle contractions. However, preventing an active contraction through deep anesthesia is different from blocking the "active tonus" with a NMB.
